An old school guy who still enjoys listening to some of his CDs in a car that doesn't have a built in CD player. I connected a portable player to the system but didn't know how to install it. At first I thought of attaching it somewhere with Velcro, but accessing it while riding was an issue. Then I saw this product at Revain. It's more versatile than comparable products - easily adjustable in width, height etc. and holds my CD player perfectly as all the buttons are within easy reach.
